I have made light gate, small but good enough to sense the ball passings.
Used for switching on motor, but i add second one for ball collision above the lift. It must stop the lift to prevent damage.

Here i show the test how sensitive the light gate is. I can make it very sensitive or less sensitive with the adjustable resistor.

The light gate uses only cheap NE555 chip and some electronic parts.
